Andronikos III Palaiologos, commonly Latinized as Andronicus III Palaeologus, was the Byzantine emperor from 1328 to 1341. He was the son of Michael IX Palaiologos and Rita of Armenia. He was proclaimed co-emperor in his youth, before 1313, and in April 1321 he rebelled against his grandfather, Andronikos II Palaiologos. He was formally crowned co-emperor in February 1325, before ousting his grandfather outright and becoming sole emperor on 24 May 1328.
Osman I or Osman Ghazi was the founder of the Ottoman Empire. While initially a small Turkoman principality during Osman's lifetime, his beylik transformed into a world empire in the centuries after his death. It existed until shortly after the end of World War I.
Orhan Ghazi was the second sultan of the Ottoman Empire from 1323/4 to 1362. He was born in Söğüt, as the son of Osman I.
The Ottoman Turks were a Turkic ethnic group. Originally from Central Asia, they migrated to Anatolia in the 13th century and founded the Ottoman Empire, in which they remained socio-politically dominant for the entirety of the six centuries that it existed. Their descendants are the present-day Turkish people, who comprise the majority of the population in the Republic of Turkey, which was established shortly after the end of World War I.
Nicaea, also known as Nikaia, was an ancient Greek city in the north-western Anatolian region of Bithynia that is primarily known as the site of the First and Second Councils of Nicaea, the Nicene Creed, and as the capital city of the Empire of Nicaea following the Fourth Crusade in 1204, until the recapture of Constantinople by the Byzantines in 1261. Nicaea was also the capital of the Ottomans from 1331 to 1335.
Nicomedia was an ancient Greek city located in what is now Turkey. In 286, Nicomedia became the eastern and most senior capital city of the Roman Empire, a status which the city maintained during the Tetrarchy system (293–324).
The rise of the Ottoman Empire is a period of history that started with the emergence of the Ottoman principality in c. 1299, and ended c. 1453. This period witnessed the foundation of a political entity ruled by the Ottoman Dynasty in the northwestern Anatolian region of Bithynia, and its transformation from a small principality on the Byzantine frontier into an empire spanning the Balkans, Anatolia, Middle East and North Africa. For this reason, this period in the empire's history has been described as the "Proto-Imperial Era". Throughout most of this period, the Ottomans were merely one of many competing states in the region, and relied upon the support of local warlords Ghazis and vassals (Beys) to maintain control over their realm. By the middle of the fifteenth century the Ottoman sultans were able to accumulate enough personal power and authority to establish a centralized imperial state, a process which was brought to fruition by Sultan Mehmed II. The conquest of Constantinople in 1453 is seen as the symbolic moment when the emerging Ottoman state shifted from a mere principality into an empire therefore marking a major turning point in its history.
The Despotate of Epirus was one of the Greek successor states of the Byzantine Empire established in the aftermath of the Fourth Crusade in 1204 by a branch of the Angelos dynasty. It claimed to be the legitimate successor of the Byzantine Empire, along with the Empire of Nicaea and the Empire of Trebizond, its rulers briefly proclaiming themselves as Emperors in 1227–1242. The term "Despotate of Epirus" is, like "Byzantine Empire" itself, a modern historiographic convention and not a name in use at the time.
The siege of Nicaea by the forces of Orhan I from 1328 to 1331, resulted in the conquest of a key Byzantine Greek city by the Ottoman Turks. It played an important role in the expansion of the Ottoman Empire.
The Byzantine–Ottoman wars were a series of decisive conflicts between the Byzantine Greeks and Ottoman Turks and their allies that led to the final destruction of the Byzantine Empire and the rise of the Ottoman Empire. The Byzantines, already having been in a weak state even before the partitioning of their Empire following the 4th Crusade, failed to recover fully under the rule of the Palaiologos dynasty. Thus, the Byzantines faced increasingly disastrous defeats at the hands of the Ottomans. Ultimately, they lost Constantinople in 1453, formally ending the conflicts.
The Battle of Pelekanon, also known by its Latinised form Battle of Pelecanum, occurred on June 10–11, 1329 between an expeditionary force by the Byzantines led by Andronikos IIl and an Ottoman army led by Orhan I. The Byzantine army was defeated, with no further attempt made at relieving the cities in Anatolia under Ottoman siege.
The Battle of Bapheus occurred on 27 July 1302, between an Ottoman army under Osman I and a Byzantine army under George Mouzalon. The battle ended in a crucial Ottoman victory, cementing the Ottoman state and heralding the final capture of Byzantine Bithynia by the Ottomans.
Halil İnalcık was a Turkish historian. His highly influential research centered on social and economic approaches to the Ottoman Empire. His academic career started at Ankara University, where he completed his PhD and worked between 1940 and 1972. Between 1972 and 1986 he taught Ottoman history at the University of Chicago. From 1994 on he taught at Bilkent University, where he founded the history department. He was a founding member of Eurasian Academy.
The Byzantine Empire was ruled by the Palaiologos dynasty in the period between 1261 and 1453, from the restoration of Byzantine rule to Constantinople by the usurper Michael VIII Palaiologos following its recapture from the Latin Empire, founded after the Fourth Crusade (1204), up to the Fall of Constantinople to the Ottoman Empire. Together with the preceding Nicaean Empire and the contemporary Frankokratia, this period is known as the late Byzantine Empire.
The Palaiologan army refers to the military forces of the Byzantine Empire under the rule of the Palaiologos dynasty, from the late 13th century to its final collapse in the mid-15th century. The army was a direct continuation of the forces of the Empire of Nicaea, which itself was a fractured component of the formidable Komnenian army of the 12th century. Under the first Palaiologan emperor, Michael VIII, the army's role took an increasingly offensive role whilst the naval forces of the empire, weakened since the days of Andronikos I Komnenos, were boosted to include thousands of skilled sailors and some 80 ships. Due to the lack of land to support the army, the empire required the use of large numbers of mercenaries.
The Battle of Dinboz or Dimbos(Turkish: Dimbos Muharebesi) took place between the Ottoman Beylik and the Byzantine Empire in 1303.
Halil Bey (1347–1362) was an Ottoman prince. His father was Orhan, the second bey of the Ottoman beylik. His mother was Theodora Kantakouzene, the daughter of Byzantine emperor John VI Kantakouzenos and Irene Asanina. His kidnapping was an important event in 14th century Ottoman-Byzantine relations. He was killed by his brother Murad I.
The Siege of Kulacahisar or Raid of Kulacahisar was a battle fought between the Byzantines and the Turks under the command of Osman Gazi in 1285.
